Hi,

I'm converting my Optimum BF20L mill to CNC and want to use a servo as spindle motor using step direction signals. The problem is my cnc4pc M16D board (with C78 interface) supports 5v step dir logic sinal but the servo drive (ABB e150) wants 24v step dir logic.

What is the easiest way to convert 5v signal to 24v signal?

Thanks in advance,
Suat
